This paper analyzes the influence of excitation in the experimental determination of flux linkage vs. current vs. position relationship of a switched reluctance motor. Results of the experimental characterization of the SRM in the cases of rectangular bipolar excitation, rectangular unipolar excitation and sinusoidal excitation are compared. An equivalent model of a motor phase including magnetic...
A knowledge of the electromagnetic characteristics of switched reluctance motors (SRM) is crucial for the simulation, analysis, control and development of drive systems based on these machines. Various experimental methods for determining flux-linkage-current-position characteristics can be found in the literature. References relating to the experimental determination of torque-current-position characteristics...
The paper describes an experimental method to identify the equivalent circuit parameters of a switched reluctance motor including non ideal effects associated with the magnetic core. The proposed method avoids the use of large capacitors or batteries to reach values of current that guarantee the saturation of the magnetic core, and minimizes the number of power electronic devices. The experimental...
FE simulation data provides information about magnetic properties corresponding to a range of foreseen current excitation and rotor positions. This information needs further processing to derive other electric parameters, among which, inductance plays an important role for simulation and modeling purposes. This paper describes this process looking for analytical expressions and evaluating the incidence...
The present and future market for motors places a high value on operating efficiency, reliability, variable-speed operation, low running temperature, quiet operation, and low cost. Permanent-magnet (PM) motors are now able to meet these market expectations across an increasing range of ratings. Compared to the prolific induction motor, PM motors provide the attributes of efficiency, reliability, etc...
